Is there a way to decompile the binary from an IPhone app. I jailbroke my IPhone and was surprised to find other app's dbs wide open to be copied. So I exported my most important table and hardcoded it into code. Instead of loading table into array from a db I just generated code to fill the array and kept only the most basic DB info so relationships still work. Took a while but now works fine.
I was just wondering am I safe, could someone decompile the binary for the app easily and extract the data. In Java its easy to decompile *.class files though thats bytecode where I presume iphone apps are more low level.
I know IPhone sdk 4 can mark files as secure. Anyone know can this be overridden by jailbreaks or is this an unix lock?
To be honest Apple couldn't secure a brick. The iPhone has been almost continuously jail-breakable seance the beginning. Users (read hackers:) have more control over the device than developers. There is no way that you can truly secure content on the device. If encryption is used, there is nothing keeping the attacker from obtaining the key. (He has control over all libraries and can hook any function call he wants.)
It is common to see developers fall back on Security Though Obscurity, and I'm not going to entertain these ideas. If there is data on the device, a hacker can and will make a copy of it.
